FOLDING HARROI/V To all whom it may concern:

Be zit known that I, VERIIC W. WAYNERT,

1 a Citizen of Canada, residing in Mason, Bayfield county, I/V1scons1n, have invented certain new and useful Improvementsin Folding Harrows, of which the following is a Specification.

My lnvention relates to the type of harrow thatis provided with wheels or vehicle .1; The object ofthe present invention is to' provide improvements in this .typeof 1131* attachments and having one section con- Structed and arranged to carry the other sections in driving to or from a field.

row, and the invention consists'inthe novel construction, combination and arrangement of parts, all as hereinafter describedin de- 1; tail, illustrated in the accompanying drawis a perspective view of the five sections folded up over the middle section, the latter ing and incorporated in the appended claims. j j I In the drawingffFigure 1 is a plan view of the middle, or vehicle sectionlof a harrow embodying my invention. "Fig. 2 is a section taken on line 22 ofFig. 1. Fig. 3 is areduced plan view of acomplete harrow of five sections minus the teeth or pins. Fig.4

having its wheelsand runners projected to carry said middle section with its load of the other four sections.

In the several views 2, 3, 4, 5 and 6 represent metal bars made of iron tubes and having therein holes for bolt-eyes 7 fastened by nuts 8 toreceive, and clamp fast the usual harrow teeth 9 some of which are shown in Fig.2.

The bars 2 to 6 are revolubly mounted in cross-bars 10, 11, 12, and 14 and are rotatable to place the teeth 9 in a substantially horizontal position and swing bearings for wheels 15 and 16 and runners 17 and 18 into a substantially vertical position, as thelatter are shown in Fig. 4. The bearings for the larly formed parts 21, 22, 23 and 24 on the bars 5 and 6. The tooth bars 2 to'6 are turned by meansof cranks 25, 26, 27, and 28 secured axially to the bars and having their wrist-pins 29'pivoted to an actuating bar 30 which is moved longitudinally by means of a lever 31 secured to the bar 3 which serves as the axis of rotation for said lever. The lever 31 is pivotedto the bar 30 at 32 Specification of Letters Patent.

and is provided with the usual small finger lever 33 operating a detent adapted to en gage the notches in a quadrant 34, bolted at 35 and 36 to a bar 37 in which the bars 2, 3 and 4 are also journaled in any suitable manner. The five sections, labeled as 38,

39, 40,41, and 42 are hinged together as at 43 and 44 by blocks havinga mortise and tenon joint coupled by a bolt 45. The runners or shoes 17 and 18 are sheet metal stampings formed with upstanding lugs 46 and 47 serving as lower journal bearing members for the journal portions of the crank portions 21 to 23. The upper bearing members are blocks 48 and 49 which are slotted .to pass over the journal portions ofthe bars 5 and 6 and-are secured to the lugs 46 and 47 by means of transverse bolts 50 and 51.

In addition to simultaneously folding up the harrow teeth out of way as the wheels and runners are swung out to facilitate the transportation features of my invention, I have obviated. the necessity of removing any part of the draft rigging for the sake of such transportation, by providing a jointed draw-bar composed of sections 52, 53, 54, 55, and 56 having at their ends mortises 57 and 58 and tenons 59, 60, and 61 held together by bolts 62. The sections 52 to 56 are each of a length corresponding substantially to the width of a section so that the draw-bar may be folded up with the sections as in Fig. 4 without necessitating its removal from connecting chains 63, 64, 65,

and 66, connecting the sections with said draw-bar. The usual double-tree (not shown) is coupled to a ring 67 from which chains branch out to different sections, a chain 68 being shown extending to the middle section 54 and chains 69 and 7 O to the sections 53 and 55. I

71 is the usual clevis for making the chain anddraw-bar connection. The construction of the middle section is also adapted for the side sections 38, 39, 41 and 42 for the purpose of tilting the teeth at different angles by merely omitting the wheels and runners from these sections, and where the harrowconsists of one section 40, as well as when consisting of the five sec- ,tions, swinging up the teeth at the same time as the wheels and runners are swung down obviates the necessity of such large wheels and high runners as if the section 40 were to be made to clear the ground with aswvell vfor, say, a barrow of three sections,

' Fig. 4. The pu pose of the runners 17 and harrow sections constructed and arranged ,1

all the teeth therein projecting in their normal positions. The lever operation also'becomes easier, and with the horizontal teeth projecting with their points rearwardly even a slight elevationof the middle section on its Wheels and runners Will enable it to clear uneven ground Without getting caught or scratching up soilor lawn. 'All' the parts being left intact ready for instant service, including the vdraw-bar 54, the usual troubles of hunting for'separated parts the following season are obviated.-

Obviously the construction serves equally the side sections in that event leaning againstqieach other ;:and presenting When folded up for transportation to the storage shed substantially the same appearance as 1.8 is to prevent the folded up structure to runagainst the draft animals in driving down grade, as Wouldbbe apt to happen if Wheels occupied the place of the runners. In other words, for thisspecial purpose the load is lightened by means of Wheels sufiiciently for this special purpose and yet not sufficiently-to cause accidents by the use of Wheels.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a plurality of to fold up on a middle sectionybf Wheels on said middle section, and means for simultaneously tilting'said Wheels tilting the harrow teeth of said section into a substantially horizontal'position and applying a moderate brake for said Wheels, said Wheels being nor mally supported on said harrow'and' tilted into position to support said harroW partly.-
